How IDEC Advances Your Data Center And The Cooling Process

Data Centers

PrintThrough it all, managers are continuously looking for ways to optimize data center operation and utilize cooling strategies that can improve operating efficiency. Today we discuss a new kind of cooling options for modern data center operators. Indirect Evaporative Cooling (IDEC) has become a proven approach for highly efficient and cost-effective data center cooling. Not only does it help reduce humidity fluctuations and filtration requirements for white space; it also can maximize white space by not taking up room in the white space when used in rooftop or end-on outdoor installations. An advanced IDEC unit such as the Nortek Air Solutions Cool3 ™ unit is designed to have a compact footprint and flexible configuration options for even more installation advantages.
To better understand IDEC, let’s look at the three operating modes of the Cool3 IDEC unit which can save operating costs year-round:
1. Economizer mode, winter. Heat exchanger device covers 100% of load, DEC and DX are off.
2. Evaporation mode, summer. DEC turned on, providing indirect evaporative cooling. DX is off.
3. Evaporation + DX mode, extreme heat and humidity. Mechanical cooling trim in extreme outdoor conditions.
Staying in Control
In deploying next-generation cooling systems with multiple operating modes, you’re also integrating smart controls into the overall architecture of your cooling infrastructure. For example, the Cool3 IDEC unit’s smart digital controls prioritize the most energy efficient operating modes of the unit, allowing the unit to operate in the most cost-saving mode as often as possible. These smart controls also minimize the unit energy and water consumptions based on the outdoor air conditions and data center requirements.Furthermore, the system minimizes the hours required to mechanically cool a data center because it operates in the economizer (winter) mode for more hours during the year (depending upon location) when it is designed to take advantage of higher outdoor air dry-bulb (DB) limits or wet bulb limits. The result can be significant water consumption savings and allow for a compact DX package size.These kinds of systems create true cooling intelligence for a much more interconnected data center. Moving forward, there will be even more utilization around data center resources and greater requirements surrounding optimal performance. In deploying IDEC – you’re also deploying dynamic cooling intelligence capabilities. You have a unit which can switch between different operating modes based on the operating conditions for optimum energy and water consumptions and modulate the scavenger air flow rate to lower flow rates whenever it is possible for even more energy savings. All of this allows you to operate a data center more optimally and efficiently. Digital smart controls are the makeup of the next-generation data center architecture. You’re simplifying control mechanism while still deploying scalable cooling technologies.Water Efficiency – a New Performance Parameter
As mandatory water restrictions or higher prices for water – or both – loom on the horizon, water efficiency is as important as energy efficiency in many parts of North America. The IDEC units that manage water most effectively will contribute to a lower total cost of operation. When selecting an IDEC unit, evaluate water efficiency as much as you evaluate energy efficiency. The Nortek Air Solutions Cool3 IDEC unit offers significant improvement in water usage efficiency compared to other IDEC systems based on:

  • Less evaporative hours in a year
  • Higher water efficiency at the same operating conditions.
